ABSTRACT:
Rotary pumps wherein the conveyed fluid, e.g. foodstuffs, entering around the rotor seats, is prevented from staying there statically, by circulating part of the fluid from the high-pressure side of the pump chamber to the low-pressure side through appropriate holes or apertures disposed around the rotor seats, and by making use of the fluid pressure itself. Washing can be carried out around the seats by circulating water that is fed to the pump, instead of the fluid, after the use of the pump has been stopped. The pumps feature a fluid circulating passage between the high-pressure side and a space in a cap portion, for purposes of cleaning that space.
